摘　　要：为研究汽车正面碰撞时驾驶人坐姿对其损伤的影响,根据实车碰撞试验数据,建立车辆驾驶舱-驾驶人-约束系统的MADYMO仿真模型,并予以验证。利用仿真模型开展车速为56 km/h的100%正面碰撞试验,将假人定位并调整其参数,分析驾驶人碰撞前的8种典型姿态对其碰撞后损伤风险的影响,并对比头部损伤值(HIC)、胸部连续3 ms损伤值、胸部压缩量以及颈部、腿部的受力情况。结果表明,碰撞时驾驶人的坐姿对身体各个区域的损伤风险有较大影响;驾驶人碰撞时的纵向位置对其损伤风险影响最显著。In order to study the effect of the posture On the injury risk of driver in frontal collision, based on test data of car crash, a simulation model was built for ＂vehicle cockpit-driver-constraint system＂ by using MADYMO software, and was verified. 100% frontal collisions at speed of 50 km/h were simulated. The injury to driver having 8 kinds of different posture Was studied and analyzed after frontal collisions. The results show that the posture of driver has a great influence on the risk of injury to driver in frontal collision, and that the longitudinal position of driver has the greatest effect on the risk.
